Systems and Methods to Plan Events at Different Locations

ABSTRACT

Systems and methods are provided to specify a location of a planned event via a selection of a listing that has location information. For example, in response to a search request a listing may show a business entity at a geographic location; and the user may select the listing as a way to specify the location of a new event or an existing event. In some embodiments, one event can have multiple listings specifying multiple locations.

CROSS-REFERENCE TO RELATED APPLICATION

The present application is a continuation in part application of U.S. patent application Ser. No. 12/135,098, filed Jun. 6, 2008 and entitled “Systems and Methods to Plan Events at Different Locations,” the disclosure of which is hereby incorporated herein by reference.

FIELD OF THE TECHNOLOGY

At least some embodiments disclosed herein relate to searching and sharing information in general and, particularly but not limited to, scheduling events using data processing systems.

BACKGROUND

There are some applications that are designed to assist people in scheduling appointments, meetings and social events, such as birthday parties, etc.

For example, a calendar application running on a personal digital assistant (PDA) may allow a user to schedule an appointment on the calendar presented on the PDA device. The user may type in a description of the location of the appointment, a subject for the appointment, and a note for the appointment. The user may specify the starting time and the ending time of the appointment, and select an option to receive, from the PDA device, an alert about the appointment prior the appointment.

Some calendar applications allow the user to invite participants. For example, the user may select email addresses from a list as invitees of a meeting and type in a description about the location of the meeting and type in a separate message about the meeting. An email program integrated with the calendar application then sends email invitations to the invitees.

There are web based services that allow a user to compose a message and to invite participants to an event. A web-based user interface allows the user to type in a description of the location of the event, the email addresses of the invitee, and an invitation message. The web-based application then sends email invitations to the invitees based on the information received from the web-based user interface.

Similarly, various requirements are described which may be requirements for some embodiments but not other embodiments.

The present disclosure provides systems and methods to specify a location of a planned event via a selection of a listing that has location information. For example, in response to a search request a listing may show a business entity at a geographic location; and the user may select the listing as a way to specify the location of a new event or an existing event. In some embodiments, one event can have multiple listings specifying multiple locations. The disclosure includes methods and apparatuses which perform these methods, including data processing systems which perform these methods, and computer readable media containing instructions which when executed on data processing systems cause the systems to perform these methods.

FIG. 1 shows a system to facilitate event planning according to one embodiment.

In FIG. 1, an end user (101) uses a user terminal (103) to submit a search request over the network (105) to a communication server (104) and/or to receive search results. The network (105) may include a local area network, a wireless data communication network, a telephone network, a cellular communication network, a telecommunication network, an interactive television network, an Internet Protocol Television (IPTV) network, an intranet, or a combination of networks, such as the Internet.

A communication server (104) may include a web server (107), an email gateway (106 a), an instant messaging gateway (106 b), a telephone gateway (106 d), or a television gateway (106 e), or other types of servers, such as an application gateway (not shown) to interface with different servers. Some embodiments may use one type of communication server (104), such as a web server (107), to receive the search request and another type of communication server (104), such as a television gateway (106 e), to provide the search results. Some embodiments may use different types of communication servers (104) to service different types of user terminals (103).

In one embodiment, the web server (107) communicates with the user terminal (103) via HyperText Transfer Protocol (HTTP) and/or other types of communication protocols, such as File Transfer Protocol (FTP), Wireless Application Protocol (WAP), etc. The web server (107) may provide static web pages, dynamic web pages, and/or web services. In some embodiments, the web server (107) provides web applications to the user terminal (103) for execution in a web browser running on the user terminal (103); and the web applications may include scripts, such as Java, JavaScript, etc., for execution within an isolated environment in a browser. In some embodiments, the web server (107) may provide rich-client applications to the user terminal (103); and the rich-client application may be programmed in traditional programming languages, such as C/C++, to have full access to functions of the operating system running on the user terminal (103).

The communications server(s) (104) communicates with a location detector (111), a search engine (113), and/or a sorter (117) to process the search request and present search results based on the information stored in a data storage facility (123), such as listings (121) about business entities or public events, or other types of searchable events that are scheduled at predetermined dates and times, at corresponding geographic locations (119). In some embodiments, the location detector (111), the search engine (113), the sorter (117) and/or other modules, such as the voice recognition system (112), are servers communicating with the communication server (104) over a network, such as a local area network, an intranet, or Internet. These servers and the communication servers (104) may run on same or separate computers. In one embodiment, there may be one or more layers of application servers between the communication server (104) and the data storage facility (123) to process the business logic and data access of the rich client applications. Alternatively, application servers may be integrated with the communication servers (104), such as the web servers (107). Thus, the disclosure is not limited to a particular type of connections among the communication servers (104), the location detector (111), the search engine (113), the sorter (117), the data storage facility (123) and other modules, such as the voice recognition system (112).

In FIG. 1, the data storage facility (123) stores events (115) the end users (e.g., 101) planned. In some embodiments, the user terminal (103) stores the events (115).

In some embodiments, both the user terminal (103) and the online data storage facility (123) store the events (115) the end user (101) planned using the listings (121). When there is a data communication connection between the user terminal (103) and the online data storage facility (123), the user terminal (103) and the online data storage facility (123) synchronize their copies of the events (115) for the end user (101).

In one embodiment, the end user (101) can use the search engine (113) to select one listing (121) from the listings (121) stored on the data storage facility and use the selected listing (121) as an indicator of the location for a new event (115) or an existing event (115).

Listings (121) of businesses or people, such as restaurants, car dealers, retailer locations, service providers, gas stations, parking lots, plumbers, and the like, may have street addresses or other location parameters, such as longitude and latitude coordinates, stored as locations (119). The listings (121) may include addresses, telephone numbers, advertisements, announcements, and/or events, etc. For example, the listing (121) may be related to a public event that has a time associated with a location (119). The locations (119) may be part of the listings (121), or associated with the listings (121). In one embodiment, the listings (121) include information related to business entities at corresponding locations (119). The entities may be businesses or people. Some of the entities may be advertisers who pay advertisement fees to promote their listings (121). Some of the entities may be non-advertisers who have free listings (121).

In one embodiment, the listings (121) are accessible to the public or to registered members. The events (115) are associated with the corresponding end users (e.g., 101) who created the corresponding events (115). The web servers (107) generally limit the access to the events (115) to those who created the corresponding events (115). After the end user (101) specifies the identities of the friends or invitees with whom to share an event (115), the web servers (107) then allows the friends or invitees to access the shared event (115).

In one embodiment, the end user (101) may provide instructions to the user terminal (103) to notify the friends or invitees about the event (115) via email, short message service (SMS), voice mail, fax, or other communication channels, such as instant messaging, telephone, etc. The user terminal (103) or the web server (107) or a separate server not shown in FIG. 1, such as an application server, automatically generates the notification message based on the listing (121) by including a link to the listing (121) or a reference to the listing (121) in the notification message to show that the location of the event (115) is the corresponding location (119) of the listing (121). Thus, the friends or invitees not only have the location of the event (115), but also have the additional information of the listing (121) related to the event (115), such as the telephone number of the business entity, a web site of the business entity, a brief description of the business entity, user ratings and reviews of the business entity, etc.

In one embodiment, the communication servers (104) provide a user interface for user interaction with listings. For example, the web servers (107) may provide a user interface via static web pages, dynamic web pages, and/or web services, etc. For example, the web servers (107) may provide the listings (121) with links to detail information pages of the listings (121), such as a map, business hours, driving directions, etc. The web servers (107) may provide user interfaces for the users (e.g., 101) to rate the listings (121), provide reviews, view reviews from other users (e.g., 101), etc. The web servers (107) may provide user interfaces to make reservations or to make purchases via the listings (121). The web servers (107) may provide user interfaces to allow the end user (101) to plan events using the listings (121), to store or bookmark selected listings, to share the listings with friends, etc. The web servers (107) can track various different types of user interactions with the listings to determine or estimate the level of user interest in the listings. The web servers (107) may provide rich client applications for execution in the user terminal to provide the user interfaces.

In one embodiment, the location detector (111) determines a location of interest to the end user (101) related to the search request. The end user (101) may explicitly specify the location of interest in the search request; and the location detector (111) extracts the location of interest from the search request.

Alternatively, the end user (101) may implicitly specify the location of interest based on a preference stored and associated with identification information of the end user (101) or the user terminal (103).

In some embodiments, the location detector (111) automatically identifies the location of interest based on determining the current location of the user terminal (103) that is used to submit the search request. For example, the location detector (111) may determine the location of the user terminal (103) based on a connection point the user terminal (103) used to access the network (105) (e.g., based on the location of a wireless network access point, a base station of a cellular communication system, or a connection point to a wired network). In some embodiments, the user terminal (103) automatically determines its current position (e.g., via a satellite positioning system, or a cellular positioning system) and transmits the determined or estimated position to the web server (107) with the search request, or provides the position in response to a request from the location detector (111).

In one embodiment, the search engine (113) retrieves listings (121) from the data storage facility (123) according to a search request. The sorter (117) ranks the listings (121) in the search results according to the distance between the location of interest and the locations (119) of the listings (121), or according to current levels of user interest in the retrieved listings (121).

For example, the web servers (107) may track various different types of user interactions with the listings (121) to determine or estimate the level of user interest in the listings (121).

In some embodiments, the data storage facility (123) stores statistics of the tracked user interactions to determine an indicator of the level of user interest in a listing (121). The indicator of user interest may be in the form of hotlist points assigned to a listing (121). In one embodiment, the hotlist points represent the popularity of a listing (121) among a set or subset of users, such as users of iPhone or iTouch from Apple, Inc. The data storage facility (123) may store the statistics as logs of web access to the listings (121) and/or other information related to the listings (121). The data storage facility (123) may store the statistics in the form of counts of various events associated with user interaction with listings (121).

For example, in one embodiment, hotlist points of a listing (121) is a function of statistics such as selection percentile, average user rating, and advertiser value.

In one embodiment, selection percentile is an n-tile partition of the number of selections of presented listings (121). For example, when the end user (101) clicks a link of a listing (121) to view a page showing additional information about the listing (121), the number of selections of the listing (121) increases by one. A listing in the group of the top 1% ranked according to the number of selections gets a selection percentile 100; and a listing at 33^(rd) percentile will get a value of 67.

In some embodiments, user selections of different links of a listing (121) to view different pages, such as a map, driving directions, details, etc., may have different weight in counting the number of selections for the determination of selection percentile. Further, each end user (101) may contribute only up to a predetermined number of selections to a listing (121) within a predetermined time period (e.g., one click per month), to prevent click abuse.

In one embodiment, advertiser value includes points and tier value for subscription listings. For example, when a listing pays a certain level of subscription, the listing has a predetermined tier value corresponding to the subscription level of the listing. Further, the listing may pay additional options, such as banner advertisements, video advertisements, etc. The options have corresponding predetermined points. Thus, advertiser value of a listing is a function of subscription level and listing options.

In one embodiment, hotlist points of a listing are a weighted sum of selection percentile, average user rating, and advertiser value. For example, hotlist points can be computed based on the following expression.

w_(a)×Selection_(Percentile)+w_(b)×Rating_(Average)+w_(c)×Value_(Advertiser)

where Selection_(Percentile) represents selection percentile; Rating_(Average) represents average user rating; and Value_(Advertiser) represents advertiser value; and w_(a), w_(b), and w_(c) are predetermined coefficients. For example, in one embodiment, selection percentile is in the range [0, 100], average user rating in [0, 5], and advertiser value in [0, 35000]; and w_(a)=0.005, w_(b)=0.08, and w_(c)= 1/350000. Thus, selection percentile contributes up to 50% of “hotness”, average user rating up to 40%, and advertiser value up to 10%; and hotlist points are in the range [0, 1]. Other combinations of weight coefficients can also be used to empirically determine the indicator of popularity among a group of end users (e.g., 101).

Other embodiments may use different types of expressions, such as Selection_(Percentile)×Rating_(Average)×Value_(Advertiser). Thus, the disclosure is not limited to particular types of expressions.

In one embodiment, the user terminal (103) is a data processing system, such as a notebook computer, a personal computer, a workstation, a network computer, a personal digital assistant (PDA), a mobile phone, a cellular phone, a television set with or without a set top box, a game console, an electronic kiosk, microprocessor-based or programmable consumer electronics, and the like.

In one embodiment, the user terminal (103) includes a web browser which allows the end user (101) to submit a search request to one of the web servers (107) for location dependent information, such as a listing (121) of businesses or people, such as restaurants, car dealers, retailer locations, service providers, gas stations, parking lots, plumbers, and the like. Alternatively, the user terminal (103) may provide the search request via other communication channels, such as email, short message service (SMS), instant messaging (IM), telephone connection, etc. For example, the user terminal (103) may provide the search request to an email gateway (106 a) via email, or to an IM gateway (106 b) via instant messaging, or to a telephone gateway (106 d) via a telephone call, or to a television gateway (106 e) via an interactive television system. Some embodiments may use other types of gateways not shown in FIG. 1, such as gateways for SMS. Thus, the disclosure is not limited to the examples or combinations illustrated in FIG. 1.

In some embodiments, the end user (101) may use one user terminal (103) to submit the search request and another user terminal (103) to receive the search results. For example, the user (101) may submit the search request via an SMS message through one user terminal (103), and receive the search results at another user terminal (103) via email. For example, the user may submit the search request via voice through one user terminal (103) and receive the search results via a web page at another user terminal (103) or at the same user terminal (103). For example, in one embodiment, the user (101) may use a mobile phone as the user terminal (103) to transmit voice information, via a data connection through the network (105) and the web server (107) (or email gateway (106 a), or IM gateway (106 b), or other data communication gateways), or a telephone connection through a telephone gateway (106 d)), to a voice recognition system (112) to formulate a search and receive a web page or email at the same user terminal (103) or at another user terminal (103) that shows the results of the search.

In one embodiment, one computer system implements the web servers (107), the location detector (111), the search engine (113), and the sorter (117). Alternatively, different processes running on one or more shared computers may implement some of the components (107, 111, 113, and 117). For example, one computing module, thread, or process may implement multiple of the components (107, 111, 113, and 117). In some embodiments, special purpose data processing systems implement the one or more of the components (107, 111, 113, and 117), such as using Application-Specific Integrated Circuit (ASIC) or Field-Programmable Gate Array (FPGA). In some embodiments, processes running according to software instructions on general purpose data processing systems, such as general purpose personal computers or server computers, can implement the components (107, 111, 113, and 117). Thus, the implementations are not limited to hardware, software, or particular combinations of hardware and software.

Different embodiments may implement the data storage facility (123) in different ways. For example, one or more data processing systems may store the information about the events (115), the locations (119) and the listings (121). For example, one or more relational or object oriented databases, or flat files on one or more computers or networked storage devices, may store the information about the events (115), the locations (119) and the listings (121). In some embodiments, a centralized system stores the information about the events (115), the locations (119) and the listings (121); alternatively, a distributed system, such as a peer to peer network, or Internet, may store the information about the events (115), the locations (119) and the listings (121).

FIG. 2 illustrates a representation of an event according to one embodiment. In FIG. 2, an event (115) includes a title (131), a note (132), one or more location references (134 and 136), and the scheduled time periods (133 and 135) associated with the locations references (134 and 136). The event (115) may optionally include one or more participant references (e.g., 137 and 138).

In FIG. 2, the location references (134 and 136) are in a form of references to listings (143 and 144) of the listings (121) on the data storage facility (123) of the web servers (107). The listings (121) have corresponding locations (119); and thus the location references (134 and 136) implicitly specify the locations (119) via association with the listings (121). In some embodiments, a copy of the location (119) of the listings (143 and 144) is also stored within the event (115) as a backup copy, which is accessible when the listings (121) are not accessible.

Using the references (134 and 136) to the listings (143 and 144) to specify the locations (119) of the events (115) provides the user (101) with convenient access to the rich information offered by the listings (143 and 144), in addition to the location information. Thus, the references (134 and 136) to the listings (143 and 144) integrate the event planning and the information resource available from the web servers (107), enrich user experience and simplify the event planning process.

In one embodiment, when the listing (121) is about an event that has an associated time period, the user planned event (115) uses the time period of the event listing (121) as the time period of the user planned event (115). For example, when the listing B (114) has a time period for an event announced by the listing B (114), the user planned event (115) has the time period B (135) that is the same as the time period for the event announced by the listing B (114). In one embodiment, the user planned event (115) stores the time period B (135) corresponding to the time period for the event announced by the listing B (114). In another embodiment, the user planned event (115) stores the time period reference (not shown) to indicate that the time period of the user planned event (115) corresponds to the time period for the event announced by the listing B (114).

Thus, the user terminal (103) or the web server (107) allows the user (101) to incrementally build up the content of an event (115) by simple selection of a listing (121) while searching or viewing businesses listings (121) or published event listings (121). The end user (101) can add the listing (121) into an event (115) with a selection of a user interface element. Thus, the end user (101) does not have to copy and paste information by going back and forth between different applications. The user terminal (103) or the web server (107) allows the user (101) to easily collect information related to locations (119) into a planned event (115).

In FIG. 2, the participant references (137 and 138) point to the entities (141 and 142) in an address book (125). In one embodiment, the user terminal (103) and/or the data storage facility (123) stores the address book (125). For example, in one embodiment, the address book (125) is accessible via the web servers (107).

In one embodiment, the end user (101) can insert the references (134 and 136) to the listings (143 and 144) into the event (13) by selecting from listings (121) presented on the user terminal (103). The user terminal (103) may present the listings (121) in response to a search request from the end user (101), or in response to the end user (101) browsing a category of listings (121). The end user (101) can also specify participants (137 or 138) by selecting from the address book (125). Alternatively, in some embodiments, the end user (101) may type a description to specify some locations without using references (134 and 136) to listings (121), or manually enter the contact information of some participants without using the address book (125).

In one embodiment, without specifying a keyword, the end user (101) may request a list of a subset of the listings (121) that have corresponding locations (119) near the current location of the user terminal (103) and that are ranked with top levels of user interest. The end user (101) then selects one from the subset of the listings (121) as a location of the event (115).

FIG. 3 illustrates a user interface to search and present listings of locations according to one embodiment. In FIG. 3, a user terminal (e.g., 103) provides a search user interface (150), which includes an input box (161) to receive one or more keywords, and an input box (163) to receive a location of interest. The end user (101) may alternatively use the icon button (165) to select the location of interest from a list of bookmarked locations.

In one embodiment, a bookmarked location can be a listing (121) the end user previously added to a list of favorites. The listing (121) has a location (119); and the bookmarked listing (121) represents the location (119) corresponding to the listing (121). An end user (101) can select the bookmarked listing (121) as a way to specify a location of interest. For example, the end user (101) can select the bookmarked listing (121) to search for other businesses near the location of the bookmarked listing (121).

In one embodiment, the end user (101) may select an entry of an address book to specify the location of interest in the input box (163). In one embodiment, the end user (101) may select a location from an interactive map.

In FIG. 3, after the end user (101) specifies the keyword in the input box (161) and the location of interest in the input box (163), the end user (101) can select the search button (167) to search for listings (121) of businesses that match the keyword and that are located near the location of interest. The end user (101) may select the icon button (169) to request listings (121) of “hot” businesses that match the keyword and that are located near the location of interest.

In one embodiment, “hot” businesses are those who have high levels of user interest. The sorter (117) may sort the search results according to the levels of current user interest for presentation on the user terminal (103) via the web servers (107).

In one embodiment, “hot” businesses are those who are popular among a group of end users (101), such as the end users (101) of a particular type of user terminals (103), such as the end users (101) of iPhone or iPod Touch from Apple, Inc., end users (101) of interactive television (e.g., via U-verse from AT&T), end users (101) of a type of web browser, etc.

After the search interface (150) receives the selection of the search button (167) (or the icon button (169) for popular listings (121)), the user terminal (103) submits the search request to web server(s) (107).

In one embodiment, the end user (101) may select the “hotlist” button (169) without specifying a keyword in the input box (161) and/or a location of interest in the input box (163). When the location of interest is not specified, the location detector (111) detects or estimates the current location of the user terminal (103) as the location of interest. When no keyword is specified in the input box (161), the search engine (113) performs the search based on the location of interest; and the search results are not limited to a particular category or keyword. The search engine (113) and/or the sorter (117) can select or order the listings (121) based on the level of user interest in listings (121) near the location of interest.

In one embodiment, the end user (101) implicitly specifies the location of interest based on the location of the user terminal (103), or based on a preference setting of the end user (101). In one embodiment, the location detector (111) determines the location of the user terminal (103) or the preference setting of the end user (101); and the input box (163) presents the location determined by the location detector (111) for verification and/or for modification.

For example, the user terminal (103) (e.g., with a global positioning system (GPS) unit) or the location detector (111) can automatically determine the current location of the user terminal (103) that presents the search user interface (150). The input box (163) displays the automatically determined location of the user terminal (103) as a default location; and the user may specify an alternative location via the input box (163) (or via the icon button (165)).

In FIG. 3, the user interface (150) presents the search results under the input boxes (162 and 163). In the example illustrated in FIG. 3, the user interface (150) presents listings (121) of business products and services in response to a search request.

In FIG. 3, the user interface (150) presents the listings (121) in an order according to the distance to location of interest.

After the end user (101) enters a location for the user planned event, the user terminal (103) displays an icon selectable to delete the location. Further, a start/end field appears below the location information. In one embodiment, the default start time is set to the next hour and the duration is one hour. For example, if the current time is 3:15 pm and the end user (103) adds a location to a user planned event (115), the default time at that location is 4 pm-5 pm. If there is already a location in the user planned event (115), the default start time is the end time of the last location added and the duration is one hour. The user can manually edit the start and end time for the location, if the default time is not desired.

If the user selects the icon to add a friend, the user terminal (103) presents an A-Z vertical shortcut list with contacts in an address book of the end user (103). The end user (103) can select a friend with one email address already in the address book to add the friend into the recipient list of the user planned event (115). If the selected friend has multiple email addresses, the user terminal (103) allows the end user (103) to select one or more from the email addresses of the selected friend for the user planned event (115). If the selected friend does not have an email address in the address book, the user terminal (103) can prompt the end user (103) to provide an email address, or to add the selected friend without an email address.

In some embodiments, the end user (103) can also SMS messages to inform friends of the user planned event (115). The end user (103) can select the cellular phone numbers of the friends from the address book into the user planned event (115) in a way similar to the selection of email address of friends.

After the end user (103) adds a friend to the user planned event (115), the user terminal (103) displays an icon selectable to remove the friend from the user planned event (115).

After the end user (103) creates a user planned event (115), the end user (103) can select the user planned event (115) from a list of user planned events (115) for viewing or for editing.

FIG. 13 shows a method to plan an event (115) using a selected listing (121) according to one embodiment. In FIG. 13, a data storage facility (123) stores (251) a plurality of listings (121), which are accessible to an end user (101) via web servers (107). After a search engine (107) receives (253) a search request from a user (101) via the user terminal (103), the network (105) and the web severs (107), the search engine (107) identifies (255) a subset of the listings (121) according to the search request. The listings (121) may provide contact information of a business entity, such as a telephone directory listing (121) of the business entity.

After the user terminal (103) presents (257) a listing (121) of the subset together with a user interface element (e.g., 177, 215, 223 or 225), the user terminal (103) receives (259) a selection of the user interface element (e.g., 177, 215, 223 or 225) to add the listing (121) to an event (115) as an indicator of location for the event.

In one embodiment, the user interface element is associated with the listing (121), as the icon button (177) illustrated in FIG. 3; and when the user interface element is selected, the listing (121) is selected from the subset.

In one embodiment, the user interface element is not associated with a particular listing (121), as the icon button (215, 223 or 225) illustrated in FIG. 5 or 6. When the user interface element (215, 223 or 225) is selected, the user terminal (103) or the web server (107) uses the listing (121) that has been selected from the subset (e.g., selected via highlighting, or selected for display in a separate web page) as a location of the event (115).

In one embodiment, the web server (107) associates the user interface element with the listing (121). For example, the web server (107) may determine whether a listing (121) includes information specifying a geographic location, and provide the user interface element (e.g., 177) with the listing (121) in response to a determination that the listing (121) includes information specifying a geographic location (119). Alternatively, an application running on the user terminal (103) may determine whether to present the user interface element (e.g., 177) based on whether the listing (121) includes information specifying a geographic location (119).

If the operation (261) determines that the listing (121) is selected by the end user (101) for a new event, the user terminal (103) or the web server (107) creates (263) a new event (115) in response to the selection. If the operation (261) determines that the listing (121) is not selected for a new event, the user terminal (103) or the web server (107) presents a user interface to receive (265) a user selection of an event from a list of existing events (115). The user terminal (103) or the web server (107) then adds (267) to the event (115) a reference (e.g., 134 or 136) to the listing (121) as a location of the event.

In one embodiment, an event (115) is limited to have one location; and the selected listing (121) is used to replace the existing location in the event (115). In another embodiment, an event (115) can have more than one location; and the selected listing (121) is added to the existing event (115) in addition to one or more existing locations in the event (115).

In one embodiment, the user terminal (103) or the web server (107) generates a message (e.g., as illustrated in FIG. 12) using the listing (121) to provide information about the location of the event (115) represented by the reference (e.g., 134 or 136) to the listing (121). The user terminal (103) or the web server (107) then transmits the message to one or more communication contacts associated with the event. The message may be an electronic mail message, a short text message, a voice mail message, an instant message, or a fax message. In one embodiment, the message includes a link to the listing (121) hosted on a web server (107).

In one embodiment, the user terminal (103) is a mobile communication device which presents the user interface element (e.g., 177, 215, 223 or 225). The web server (107) remote to the mobile communication device, or another server not shown in FIG. 1, generates the message using the listings (121) stored on the data storage facility. During the scheduling of the event the end user (101) may provide a note (132) and a title (131) for inclusion in the message.

In one embodiment, the user terminal (103) provides a user interface that allows the end user (101) to select the one or more communication contacts from an address book (125). The user terminal (103) or the web server (107) associates the one or more communication contacts with the event (115) via the participant references (e.g., 137 or 138). When the end user (101) instructs the user terminal (103) to share the planned event (115), the user terminal (103) or the web server (107) automatically generates and sends messages to the one or more communication contacts.

In one embodiment, after receiving an invitation from an event planner, an invitee can access an event (115) stored on the data storage facility (123), make proposed changes to the event (115) and request the web severs (107) to notify the event planner and/or other invitees about the changes. Upon notification, the event planner may confirm/accept the changes, or reject the changes.

In one embodiment, the user terminal (103) or the web server (107) creates or modifies the event (115) in a calendar of the end user (101) hosted on the user terminal (103) or the web server (107), using the listing (121) selected by the end user (101). The end user (101) can associate a scheduled time period with the location represented by the reference (e.g., 134 or 136) to the listing (121). When there are multiple locations in an event (115), the end user (101) can specify a different time period for each of the locations planned in the event (115).

FIG. 14 illustrates a data processing system which can be used in various embodiments. While FIG. 14 illustrates various components of a computer system, it is not intended to represent any particular architecture or manner of interconnecting the components. Other systems that have fewer or more components may also be used.

In one embodiment, a server data processing system as illustrated in FIG. 14 is used as one of the web server(s) (107), a location detector (111), a search engine (113), a sorter (117), and/or a storage facility (123) for storing events (115), locations (119) and listings (121), etc. In some embodiments, one or more servers (e.g., 107, 111, 113, 117, 123) of the system can be replaced (e.g., by a system designer) with the service of a peer to peer network of a plurality of data processing systems, or a network of distributed computing systems. The peer to peer network, or a distributed computing system, can be collectively viewed (e.g., by the reader of the description) as a server data processing system.

In one embodiment, a user terminal (103) is a data processing system as illustrated in FIG. 14 to provide the user interfaces illustrated in FIGS. 3-11.

In FIG. 14, the data processing system (301) includes an inter-connect (302) (e.g., bus and system core logic), which interconnects a microprocessor(s) (303) and memory (308). The microprocessor (303) is coupled to cache memory (304) in the example of FIG. 14.

The inter-connect (302) interconnects the microprocessor(s) (303) and the memory (308) together and also interconnects them to a display controller and display device (307) and to peripheral devices such as input/output (I/O) devices (305) through an input/output controller(s) (306). Typical I/O devices include mice, keyboards, modems, network interfaces, printers, scanners, video cameras and other devices which are well known in the art. In some embodiments, when the data processing system is a server system, some of the I/O devices, such as printer, scanner, mice, and/or keyboards are optional.

The inter-connect (302) may include one or more buses connected to one another through various bridges, controllers and/or adapters. In one embodiment the I/O controller (306) includes a USB (Universal Serial Bus) adapter for controlling USB peripherals, and/or an IEEE-1394 bus adapter for controlling IEEE-1394 peripherals.

The memory (308) may include ROM (Read Only Memory), volatile RAM (Random Access Memory), and non-volatile memory, such as hard drive, flash memory, etc.

Volatile RAM is typically implemented as dynamic RAM (DRAM) which requires power continually in order to refresh or maintain the data in the memory. Non-volatile memory is typically a magnetic hard drive, a magnetic optical drive, an optical drive (e.g., a DVD RAM), or other type of memory system which maintains data even after power is removed from the system. The non-volatile memory may also be a random access memory.

The non-volatile memory can be a local device coupled directly to the rest of the components in the data processing system. A non-volatile memory that is remote from the system, such as a network storage device coupled to the data processing system through a network interface such as a modem or Ethernet interface, can also be used.

In this description, various functions and operations may be described as being performed by or caused by software code to simplify description. However, those skilled in the art will recognize that what is meant by such expressions is that the functions result from execution of the code/instructions by a processor, such as a microprocessor. Alternatively, or in combination, the functions and operations can be implemented using special purpose circuitry, with or without software instructions, such as using Application-Specific Integrated Circuit (ASIC) or Field-Programmable Gate Array (FPGA). Embodiments can be implemented using hardwired circuitry without software instructions, or in combination with software instructions. Thus, the techniques are limited neither to any specific combination of hardware circuitry and software, nor to any particular source for the instructions executed by the data processing system.

While some embodiments can be implemented in fully functioning computers and computer systems, various embodiments are capable of being distributed as a computing product in a variety of forms and are capable of being applied regardless of the particular type of machine or computer-readable media used to actually effect the distribution.

At least some aspects disclosed can be embodied, at least in part, in software. That is, the techniques may be carried out in a computer system or other data processing system in response to its processor, such as a microprocessor, executing sequences of instructions contained in a memory, such as ROM, volatile RAM, non-volatile memory, cache or a remote storage device.

Routines executed to implement the embodiments may be implemented as part of an operating system or a specific application, component, program, object, module or sequence of instructions referred to as “computer programs”. The computer programs typically include one or more instructions set at various times in various memory and storage devices in a computer, and that, when read and executed by one or more processors in a computer, cause the computer to perform operations necessary to execute elements involving the various aspects.

A machine readable medium can be used to store software and data which when executed by a data processing system causes the system to perform various methods. The executable software and data may be stored in various places including for example ROM, volatile RAM, non-volatile memory and/or cache. Portions of this software and/or data may be stored in any one of these storage devices. Further, the data and instructions can be obtained from centralized servers or peer to peer networks. Different portions of the data and instructions can be obtained from different centralized servers and/or peer to peer networks at different times and in different communication sessions or in a same communication session. The data and instructions can be obtained in entirety prior to the execution of the applications. Alternatively, portions of the data and instructions can be obtained dynamically, just in time, when needed for execution. Thus, it is not required that the data and instructions be on a machine readable medium in entirety at a particular instance of time.

Examples of computer-readable media include but are not limited to recordable and non-recordable type media such as volatile and non-volatile memory devices, read only memory (ROM), random access memory (RAM), flash memory devices, floppy and other removable disks, magnetic disk storage media, optical storage media (e.g., Compact Disk Read-Only Memory (CD ROMS), Digital Versatile Disks (DVDs), etc.), among others. The instructions may be embodied in digital and analog communication links for electrical, optical, acoustical or other forms of propagated signals, such as carrier waves, infrared signals, digital signals, etc.

In general, a machine readable medium includes any mechanism that provides (i.e., stores and/or transmits) information in a form accessible by a machine (e.g., a computer, network device, personal digital assistant, manufacturing tool, any device with a set of one or more processors, etc.).

In various embodiments, hardwired circuitry may be used in combination with software instructions to implement the techniques. Thus, the techniques are neither limited to any specific combination of hardware circuitry and software nor to any particular source for the instructions executed by the data processing system.

Although some of the drawings illustrate a number of operations in a particular order, operations which are not order dependent may be reordered and other operations may be combined or broken out. While some reordering or other groupings are specifically mentioned, others will be apparent to those of ordinary skill in the art and so do not present an exhaustive list of alternatives. Moreover, it should be recognized that the stages could be implemented in hardware, firmware, software or any combination thereof.
